I saw these new tool kits at the Porsche pop up store at the Goodwood revival a few weeks ago. The houndstooth is for a 911 the leather one is for a 356. Priced at about $600.00
I'm kicking myself for not buying one of each, but I was to lazy to carry them around all day. They did say they were only available there. I was hoping they would soon be available at dealerships. I'm not sure if porsche does short runs for events like Goodwood to test the waters.
